SPECIFICATION forming part of Letters Patent No. 641,211, dated January9, 1900. Application filed July 31,1899. Serial No. 725,676. (Nospecimens.)

subject of the Queen of Great Britain, residllO ing at 17 Seaside,Eastbourne, in the county of Sussex, England, have invented certain newand useful Improvements in Binding Books, of which the following is aspecification.

This invention has for its object to provide new and improved means forbinding or connecting the leaves of books, pamphlets, and v the likewhereby wire and thread fastenings are avoided and each leaf is securedin such manner that the book or pamphlet can be opened and spread flatat any point Without breaking or tearing. V

For the purpose of my invention l stamp and sever a portion of each oreach alternate leaf with, say, a dovetail shape of cutting near the backedge, terminating the end slits at the creasing part, so that thestampedy loose portion formsa kind offlap capable of beingpushedoutwardly, which l then glue or paste together to form asection-41. e. four or more double leaves. Thus any number of sectionscan be connected to constitute a pamphlet or book ready for thereception of the cover without any sewing or stitching, each leaf beingsecurely held and the pamphlet being opened out flat for reading orother purpose. I have referred to each leaf as being so stampedorprepared to `form the flaps; butthe stamping may bein one leaf only ofa double leaf, and when the flaps of several of such sections of doubleleaves are prepared l prefer that the stampings be made at two or moredifferent partsv in the series, so the bulk of flaps are arranged atdifferent parts'of the back, and thus obviate an excess of bulginess atany one part. Some of the stamped slits may be only at the middle of thecreasing-line and others can be stamped near the top and bottom,respectively, or at top or at bottom only, the length of the slitinsuring the absolute connection of all the leaves of which the pamphletor book is composed. The flaps when cemented in series may have acloth-back liner glued to them to give the back a neat appearanceprevious to the covers being applied.

My invention will be understood by the aid of the annexed drawings.

Figure l is a face view of a single leaf of paper with three dovetailedshapes of cuts from which aps are formed when folded back for attachmentto corresponding flaps of other sheets orleaves of paper; Fig. 2,acorresponding view of a single leaf or sheet of paper or other materialin Whicn the cutting of the flaps is reversed, the dotted lines, as inFig. 1, showing the fold-back flaps. Figs. 3 and 4 show the sheetsrepresented at Figs. l and 2, respectively, with theflaps foldedback-and exposing the gaps or spaces fromwhich the flaps have beenremoved by the back-folding operation Fig. 5, a perspective view of adouble or folded 'sheet of paper from either leaf of which the flaps maybe cut or partly from one leaf and partly from the other, so that whensuch flaps are folded back the several flaps of the several leaves canbe glued or pasted to one another to connect the several insets orsections of which tho pamphlet or book is to be composed. v

The several letters of reference apply to all the figures.

According to Fig. 1, (the dovetail cut through the paper A,) the flap Bhas `its narrowed part next the edge O of the paper. Consequently thewider portions D D of the flaps B are ready when folded to appear beyondthe edge to be pasted or glued to corresponding or other flaps of theadjoining sheet, leaf, or piece'of paper, and so on, determined by thethickness of the pamphlet or book.'-

Referring to Fig. 2, the flap B has its widest part D D next the edge Oof the paper A, and its narrowed edge E E is farthest from the edge. Bythis means less glue or paste at the fold-back portion of the flap Blwould be required.

The manner of cutting and forming the flaps from single leaves, asdescribed and shown, somewhat thickens the back of the pamphlet or bookwhen made up or bound, because a portion of each flap lies on the leaf;but by entting and forming the flap from a foldable or doubleleaf thecutis from the foldingcrease F and the flap forms 'an extensiontherefrom, which flaps in quantity and glued or pasted IOO together fromdierent parts in the height of the book are rolled or clustered betweenthe back of the book and the back of the binding and not observable-when the binding is completed.

p What I claim, anddesire to secure by Letters Patent, is-

l. A bound book or pamphlet having the leaves slitted at the backportions to form flaps integral therewith which are folded outwardlytherefrom and united toA one another, substantially as and for thepurposes described.

2. A bound book or pamphlet having the leaves slitted at their backportions to form foldable flaps integral therewith which are foldedoutwardly and cemented to one an` other, substantially as and for thepurposes described.

3. A bound book or pamphlet having doubled leaves-slitted at theirfolding-lines to form aps integral therewith which are folded outwardlyat said folding-lines and secured to one another, substantially as andfor the purposes described.

4. A bound book or pamphlet having leaves slitted at their back portionsto form groups of superimposed flaps integral with the leaves which arefolded outwardly and the flaps of each group cemented to one another,substantially as and for the purposes described.

In testimony whereof have hereunto set my hand in presence of twosubscribing Witl nesses.
